Adjustable tray

ABSTRACT

A tray for horizontally supporting a drink container, and a cooperating clamping assembly for attaching the tray to a tubular chair. The clamping assembly has two hollow cylindrical members, one of which has an end with a perpendicularly inturned flange defining a circular opening having an enlarged cross-section. Rotatably supported within this member is a disc with a transverse slot in one face. This member has an arcuate slot penetrating its wall superjacent the edge of the disc through which the shank of a locking knob passes to threaded engagement with a lock nut seated in an indentation in the side of the disc. When the locking knob is turned in one direction, the nut is drawn against the inner wall of the cylindrical member to lock the disc in position. When the knob is turned in the other direction, the nut is loosened, and the disc can then be rotated within the cylindrical member by shifting of the locking knob. The tray has an integral bayonet lug with a round, flat base segment transversely across the top of which extends a flat latch bar segment with ear-like ends which project beyond the edge of the base segment. When the disc is positioned in one particular way, the bayonet lug can be inserted in the clamping assembly so that its latch bar segment fits into the above-mentioned slot. The disc can then be rotated to another position and locked in place to secure the tray to the clamping assembly.

FIG. 3.' 60' Y ADJUSTABLE TRAY BACKGROUND OF THE INVENTION Thisinvention relates generally to tray-like holders for drinking glasses,beverage mugs, ash trays, and the like, and more particularly to suchholders which can be easily mounted on tubular patio chairs, wheelchairs, etc., for convenient use by the chair occupants.

For various reasons, outdoor furniture of the tubular aluminum varietyis widely used today on patios, around swimming pools, in backyards, andelsewhere by home owners, motel managers, campground directors, etc.Such furniture is lightweight and extremely useful for outdoor service,during which it is moved from place to place, often out of reach oftable tops or other convenient places to put glasses, mugs, bottles, ashtrays, etc. This means that the occupant of, for example, a patio chairhas no place to set his glass or place an ashtray if he is sipping adrink or smoking, hence must hold the glass or ash tray in his handcontinuously or intermittently place it on the deck or ground where itmight fall or be knocked over and is inconvenient to reach. When thechair occupant is drinking and smoking at the same time, hisdifficulties are, of course, compounded. Tubular outdoor furniture hasbeen in popular use for a great many years, and virtually everyone has,at one time or another, used such furniture while attempting to handle adrink of some sort without the aid of a nearby table, bench or otherconvenient place to put the drink between sips.

In view of the foregoing, it will be clear that there has been a longfelt need for some simple, inexpensive, and expedient way of providingthe occupants of patio chairs or the like with convenient support fordrinks and ash trays as needed. To date no one has, to my knowledge,provided any means precisely suited for this purpose, althoughvariousarrangements for the attachment of dinner trays, and the like, to thearms of chairs and chaise longues have been proposed. Such trays arerelatively large, however, and their attachment to the arms of outdoorchairs, while suitable for some purposes, is not particularly suited fordrink or ash tray support purposes. For one thing, the position of thetray is generally such as to make it somewhat awkward to move a drinkingglass, or the like, on and off of, or use an ash tray on, the tray. Foranother, the presence of the tray at the chair occupants elbow, orsometimes partially over his lap, as it is when attached to his chairarm, causes the occupant of the chair to feel somewhat hemmed in" whichis an uncomfortable sensation for many individuals.

SUMMARY OF THE INVENTION 1 have now provided, by this invention, asimple and compact device ideally suited for the support ofa drinkcontainer and an ash tray closely adjacent the occupant of a tubularpatio chair or the like, yet positioned where it will not crowd thechair occupant while permitting him to use it without discomfort orawkwardness. The drink and ash tray supporting device of this inventionis removably attachable to a leg, side-brace or other tubular segment ofthe frame of a patio chair, chaise longue, or equivalent piece ofoutdoor furniture, and is tiltably adjustable so as to hold the drinkcontainer and- /or ash tray in a horizontal position regardless of theangle of the tubular segment of the chair frame to which it is attachedor the slope of the surface on which the chair rests. The drink and/orash tray holder is preferably of molded plastic construction, at leastfor the most part, and made up of relatively simple parts which can beeasily and inexpensively fabricated and assembled, and subsequentlyinstalled on a piece of furniture with little or no difficulty byanyone, even one without mechanical aptitude, using only an ordinaryscrewdriver. The drink and/or ash tray holding device lends itself toattractive packaging and sale at a price low enough so that anyone canafford it, and it is, by virtue of its simplicity of construction andmethod of assembly, readily movable from one chair to another asdesired.

The drink and/or ash tray holder of this invention is, in its preferredform, made up of a relatively small holding tray with a pair ofdepressions of differing depth, adapted to receive a flanged ash tray orthe like and a drink container, and a clamping assembly attachable to atubular patio chair, or the like, for support of the tray in a positionof convenient use by the occupant of the chair. The clamping assemblycomprises a pair of generally cylindrical clamp members of equalcrosssectional diameter, each having two semicircular notches in one endwhich cooperate to permit the members to be brought together in embraceof a segment of the frame of said tubular patio chair. The two clampmembers are preferably provided with screw fastening means for holdingthem securely to the tubular chair frame when fitted together around asegment thereof as described. The clamp members are of generally hollowconstruction and one has a relatively thick, preferably plastic, discrotatably and coaxially mounted therewithin. The clamp member housingthe disc has a pair of diametrically opposite tits on its inner wallpositioned to keep said disc at its proper axial location therewithin.The outer (as opposed to semicircularlynotched) end of this member hasan inturned flange, perpendicular to its cylindrical wall, which definesa round opening with a transverse, central enlargement adapted toreceive a bayonet lug (to be described below) on the holding tray. Theface of the aforesaid disc confronting said inturned flange has arelatively wide slot running transversely thereacross, sized for apurpose hereinafter appearing.

Running circumferentially around a portion of the cylindrical wall ofthe clamp member housing the aforesaid disc is a penetrating slotsuperjacent the edge of the disc. The disc has a flat-bottomedindentation in its side adapted to seat a square lock nut. The threadedshank of a locking knob (a screw with a knurled head by means of whichit can be manually turned) is engageable with the nut through theaforesaid slot in the wall of said clamp member. The disc can berotatably adjusted within said clamp member by shifting the locking knobback and forth in the slot, and secured in any position of adjustment byturning the knob to tighten said lock nut against the inner wall of theclamp member.

Integral with, and extending laterally outwardly from, the aforesaidholding tray is the above-mentioned bayonet lug. This bayonet lug has araised base segment of round cross section topped by a flattendd latchbar segment with ear-like ends projecting beyond the edge of the basesegment. The latch bar segment of the bayonet lug fits through thecentral enlargement of the round opening defined by said inturned flangeof said clamp member and into the slot in said disc when said centralenlargement of said opening overlies said slot. The round base of thebayonet lug is sized to fit rotatably within the reduced portion of theopening so that insertion of the lug through the opening seats it forrotation of the disc in said clamp member, after which the disc can belocked in position by means of the locking knob to anchor the holdingtray to the clamping assembly.

It will be apparent from the foregoing that, by virtue of the uniquestructure and method of functioning of the clamping assembly of thisinvention, my novel holding tray can be readily attached to the frameofa tubular patio chair, or the like, and thereafter manually adjustedto a substantially horizontal position for use.

It is thus a principal object of the present invention to providelightweight support means for a drink and ash tray which can be easilyattached to the frame of a tubular patio chair, or the equivalent, in arelatively inconspicuous, out of the way, but conveniently accessible,position for use by the occupant of the chair.

It is another object of the invention to provide such drink and ash traysupport means of simple construction, low cost, and attractiveappearance.

Another object of the invention is to provide such drink and ash traysupport means which can be easily installed for use on a vertical,horizontal, or angled part of the frame of a tubular chair by anyonecapable of using an ordinary screwdriver.

Other objects, features and advantages of the invention will becomeapparent in the light of subsequent disclosures herein.

DESCRIPTION OF PREFERRED EMBODIMENT:

Considering now the drawing in greater detail, with emphasis first onFIG. 1, there is shown generally at T a preferred embodiment of a drinkand ash tray holding device in accordance with this invention attachedto the tubular frame of a patio chair, the frame being shownfragmentarily at C.

The holding device T has two interlocking parts, namely a drink and ashtray holding tray 12 and a clamping assembly 10, the latter designed toclamp around a part of the tubular chair frame and support the holdingtray in a horizontal position for use by a person occupying the chair.The tray 12 is preferably formed from sheet plastic of suitablecharacter for the purpose, and has two side-by-side depressions l4 and18 depending downwardly from a flat integral top 22. Suitable plasticsfor the purpose, and available techniques for forming trays and the liketherefrom, are well-known to those skilled in the art, hence need not bespecifically named or described herein. Depending perpendicularlydownwardly from the top 22 of tray 20, at the rear, is a flat wallsegment 24 connected to the underside of said top by a gusset 30 asshown in FIG. 2. Depending wall segment 24 has an integral bayonet lug26 projecting from its outer side for a purpose hereinafter made clear.Bayonet lug 26 has a raised, circular base segment 25 and a latch barsegment 28. The latch bar segment 28 is relatively flat and elongated,having a width substantially less than the diameter of the circularperiphery of base segment 25 and a length in excess of this diameter sothat its ends extend equidistantly beyond the periphery of the basesegment to form a pair of ear-like tabs 27 and 29, as best seen in FIG.4. A web 20 (see FIGS. 2 and 3) depends downwardly from the underside ofthe top 22 of holding tray 12 and integrally connects the depressions14- and 18 at their closest points, to add strength and rigidity to theholding tray structure. Depression 14 is relatively shallow, primarilyfor purposes of receiving a glass ash tray with an outwardly extendingflange around its top sized to nest snugly therewithin, such an ash traybeing shown so positioned at 16 in FIG. 1. Depression 14 can, however,be alternatively used to support a drink container, preferably one witha relatively low center of gravity such as a thick-walled mug, in lieuof an ash tray, if desired. The deeper depression 18 can be employed tosupport a drink container of any of a variety of sizes, including suchtall containers as highball glasses, beer bottles, and the like.

Clamping assembly 10 has a pair of substantially hollow, generallycylindrical clamp members 32 and 36, clamp member 32 being longer thanthe other, and forming the forward part of the clamp assembly, and clampmember 36 being shorter and forming the back of the assembly. Clampmember 36 has a rear closure 38, see FIG. 2, and a pair of alignedsemicircular notches 44 in the opposite sides of its cylindrical wall.Clamp members 32 and 36 are of equal cross-sectional diameter, and theforward member 32, like member 36, has a pair of aligned, semicircularnotches 70, 71 in its cylindrical wall. The radii of semicircularnotches 70, 71 are equivalent, and equal to the radii of notches 44 inclamp member 36. When the two clamp members 32 and 36 are fittedtogether in axial alignment, with their respective pairs of notches inconfronting relationship, these notches form aligned circular openingsthrough the resulting clamp assembly wall. This makes it possible tobring the clamp members together either side of a straight tubularmember sized to fit snugly within said circular openings. The frameworkof conventional lawn and patio chairs is formed largely from aluminumtubing ofa standardized size and I have discovered that clamp memberswith openings of one-inch diameter easily accomodate this tubing, henceare preferred for purposes of this invention. There is nothing criticalabout this particular opening size, however, and the clamp members canbe made with openings to fit tubing of any desired size within the scopeof the invention. FIG. 1 shows the clamp members 32 and 36 fittedtogether in the described manner in embrace of a vertical section of theframe of the tubular chair C.

The back clamp member 36 is provided with a pair of integraldiametrically opposite, smooth-bored cylindrical sockets 68 on its outerwall, these sockets being axially parallel to each other and to theclamp member and sized to admit, in nonthreaded engagment, a pair ofidentical screws 66, one of which can be seen in FIG. 6, for a purposehereinafter appearing. The clamp member 32 has a pair of integral,internally threaded sockets 72 and 73 at diametrically oppositepositions on its outer wall (see FIG. 2). These sockets are designed toalign with the cylindrical sockets 68 of clamp member 36, when the twoclamp members are positioned with their semicircular notches inconfronting relationship, as shown in FIG. 1, so that the two clampmembers can be secured together by means of the screws 66. Thus, as willnow be apparent, the clamp members are easily installed for use on thetubular frame of a patio chair or the like by fitting them in positionaround an appropriate part of the frame, passing screws 66 through thecylindrical sockets 68 and tightening the screws in the threaded sockets72 and 73.

Clamp member 32 has a cylindrically walled hollow space in its interior,positioned at the forward part of which is a relatively thick disc 34.The disc 34 has a relatively wide, transverse slot 52 in one face, saidslot being symmetrical about a diameter of the disc and suitably sizedfor a purpose hereinafter revealed. The disc 34 is positioned coaxiallywithin clamp member 32, and is of a thickness and diameter to precludethe possibility of tilting misalignment therewithin. The forward end ofthe clamp member, to the right as seen in FIG. 6, has an integral,inturned flange 46 extending perpendicularly from its cylindrical walland defining a circular opening 48 interrupted by a pair ofsymmetrically opposite gaps 74 and 75 which provide a transverseenlargement of the opening for a purpose described below. Set back fromthe forward face of clamp member 32 is an arcuate slot 50 whichpenetrates the cylindrical wall of the member for a portion of itscircumference and has an axis on a perpendicular crosssectional planethrough the clamp member. The disc 34 (sometimes hereinafter referred toas locking disc 34) is positioned just behind the flange 46, whichprevents escape of the disc through the forward end of clamp member 32and is prevented from backward axial migration within said clamp memberby a pair of integral projections 76 and 77 on diameterically oppositesides of the internal wall of the clamp member (see FIG. 6). Theseprojections are positioned a sufficient distance from flange 46 topermit the free rotation of disc 34 within clamp member 32, yet preventmovement of the disc from its normal position of rotation to anysubstantial extent.

The locking disc 34 has a flat-bottomed, flat-sided cut 54 in its edgespaced equiangularly from the ends of slot 52 in its forward face. Thecut 54 runs through the disc from front to rear, has sides perpendicularto the faces of the disc, and serves as a seat for a square lock nut 56.The disc, cut 54 and lock nut 56 dimensions are such that the nut fitssnugly within the cut and does not extend beyond either face of thedisc, or crowd the top of the cut to interfere with free rotation of thedisc in clamp member 32, except when tightened as hereinafter described.The nut is threaded to receive the threaded shank 62 of a knurled-headlocking knob 60 having a purpose and function soon to be revealed. Justbelow the position of the threaded opening of the lock nut 56 in thebottom of cut 54 in the locking disc is a smooth-walled socket 64 sizedto freely admit the shank 62 of the locking knob 60. When clamp member32 is properly assembled with the locking disc 34 positioned in theforward part of its hollow interior as described above, the arcuate slotSt in its cylindrical wall is positioned intermediate the two faces ofthe locking disc, the width of the slot being sufficient to freely admitthe shank 62 of locking knob 60, but less than the thickness of thelocking disc. The locking nut 56 is positioned in the cut 54 in thelocking disc, and the shank of the locking knob 60 passes downwardlythrough this nut (in threaded engagement therewith), then into thenonthreaded socket 64 in the locking disc. A metal washer 58 ispositioned around the shank of the locking knob between its knurled headand the outer wall of clamp member 32.

As will now be apparent, the locking disc 34 can be rotatably adjustedwithin clamp member 32 by movement of the locking knob 60 in slot 50 inthe wall of the clamp member. The parts of clamp member 32 are sodesigned that the slot 52 in the forward face of disc 34 is in axialregistry with the enlargement formed by the gaps 74 and 75 in the roundopening 48 defined by the flange 46 at the forward end of the clampmember when the shank of the locking knob is at one end of slot 50.These gaps 74 and 75 are of substantially the same width as slot 52 indisc 34, and otherwise dimensioned, along with the circular opening 48in clamp member 32, to admit bayonet lug 26 so that its latch barsegment 28 fits snugly within slot 52, and its circular base segment isfreely rotatable within the circular opening 48. lt will now be apparentthat the locking disc 34 can be rotated within the cylindrical shell ofclamping member 32 by merely moving the locking knob 60 back and forthwithin the arcuate slot 50. As will be further apparent, the lockingdisc can be firmly secured in any position to which it can be rotated bymerely turning locking knob 60 in the proper direction to workdownwardly through lock nut 56 until further tightening of the lockingknob draws the nut firmly against the inner wall of the clamp membershell to squeeze the shell between the nut and the washer 58 bearing onits outer surface. When the nut is thus tightened, the locking disc 34is held in a fixed position within the clamp member shell from which itcan be moved only by first loosening the lock nut to free locking knob60 for this purpose.

To install the clamping assembly on a piece of tubular furniture foruse, the clamp members 32 and 36 are first fitted around a convenientpart of the tubular frame, as described above, and fastened in positionwith the two screws 66. The loosened locking knob 60 is moved to the endof slot 50 in the wall of clamp member 32 at which the slot 52 in disc34 comes into registry with the enlarged portion of the round opening 48in the forward end of the clamp member. The bayonet lug 25 is theninserted into the end of clamp member 32 until its latch bar segment isseated in the slot 52. The tray is then adjusted to the horizontalposition through movement of the locking knob 60, and the locking knob60 is tightened. This tray adjustment brings the cars 27 and 29 of thelatch bar segment 28 of the bayonet lug at least partially behind flange46 of clamp member 32, to help interlock the tray and clamping assemblywhen the locking knob is tightened.

If it is desired to remove the tray from the clamping assembly, this canbe accomplished by loosening the locking knob, rotating the disc 34, bymeans of said locking knob, to the extreme position of the locking knobshank in arcuate slot 50 at which the slot 52 in the forward face of thedisc is in registry with the enlarged portion of opening 48 in theforward end of the clamp member, and then slipping the bayonet lug (andtray) out of said clamping assembly. The registry of the slot 52 in disc34 and the enlarged portion of the opening 48 of clamp member 32 is madeto concur with an extreme position of the locking knob shank in arcuateslot 50, as described, to permit easy removal of the tray from the fullyassembled apparatus. It is thus a simple matter to remove the tray bymerely loosening the locking knob, moving the knob to the appropriateend of the slot 50 for registry of slot 52 and the enlarged portion ofopening 48 and withdrawing the tray from the clamping assembly.

The parts making up clamping assembly 10 other than the shank of lockingknob 60, lock nut 56, washer 58 and screws 66 are preferably, but notnecessarily, of molded plastic construction. The remaining parts of theclamping assembly are preferably, but again not necessarily, of metallicconstruction.

While the novel drink and/or ash tray holding means of this inventionhas been herein illustrated and described in what is considered to be apreferred embodiment, there are, as will be appreciated, variations ofthis embodiment within the scope of the invention. Certain of thesevariations have already been mentioned, and others will occur to thoseskilled in the art in the light of present teachings. Examples of thelatter result when non-critical changes are made in the shapes ofvarious parts, or features, of the illustrated unit; equivalentmaterials of construction are substituted for the preferred materialsmentioned above; certain structural, or other, features of the unit notcritically essential to its proper use and functioning are eliminated;useful, but non-critical, hardware, or other, means are incorporated inthe illustrated unit; etc.

While the present disclosure has emphasized the use of my novel unit forthe attachment of a drink and/or ash tray holder to the frame of atubular patio chair or the like, it should be understood that the unitis not necessarily limited to this use, but can be employed in anycapacity for which its unique character suits it.

Holding means in accordance with claim 1 adapted primarily forattachment to a piece of tubular furniture, in which said segment ofrigid tubing is a part of the framework of the piece of furniture, saidsupported means is a drink holding tray, and; in which said outer shellis of generally cylindrical shape with a generally cylindrical innerwall, said internal member is a disc adapted to fit snugly but rotatablywithin said shell in coaxial relationship therewith, said disc beingsufficiently thick to remain uncanted in said coaxial relationshipwithin said shell; said slot is a transverse slot in one face of saiddisc disposed symmetrically about a diameter thereof; and said shell hasintegral retaining means for preventing substantial axial migration ofsaid disc from a predetermined position therewithin.
 3. Holding means inaccordance with claim 2 in which said bayonet lug has a substantiallyflat base segment of circular periphery and a latch bar segmentoverlying said base segment and running transversely across a midsectionthereof, said latch bar segment being of sufficient length to extendbeyond the peripheral edge of said base segment at each end to provide apair of ear-like extensions therebeyond; said outer shell has aninturned flange defining a generally circular opening at one end, whichgenerally circular opening is enlarged at diametrically opposite sidesto provide access for said latch bar segment of said bayonet lug, and isotherwise adapted to receive said base segment of the bayonet lug inrelatively snug fitting but rotatable relationship; said disc ispositioned within said outer shell with said slot facing said inturnedflange; said receptive hollow includes said slot and said generallycircular opening and is adapted to receive said bayonet lug when saidslot is in registry with the enlarged sides of said opening; androtational movement of said disc from said position of registry of itsslot with said enlarged sides of said opening when said bayonet lug ispositioned within said receptive hollow serves to interengage saidbayonet lug and clamping assembly by moving said ear-like extensions atleast partially behind said flange.
 4. Holding means in accordance withclaim 3 in which said outer shell has an axially perpendicular slotthrough its wall, superjacent the edge of said disc, running part wayaround said wall, and said moving and locking means comprises a lockingknob with a head which can be turned by hand and a threaded shank; saiddisc has an indented seat for the retention of a lock nut in its edge;said moving and locking means includes a lock nut positioned in saidseat, said lock nut being threaded to receive the shank of said lockingknob and said locking knob being positioned with its shank extendingthrough said perpendicular slot to threaded engagement with said locknut, in the assembled holding means; and said disc has a non-threaded,blind socket in the bottom of said seat beneath the center of said locknut, said socket being sized to receive the outer end of the shank ofsaid locking knob in loosely fitting non-threaded relationship, and saidshank being of sufficient length to extend into such socket for asufficient distance to permit said disc to be rotated between saidlimits in said shell by the manual shifting of said locking knob backand forth in said perpendicular slot; the parts of the assembled holdingmeans cooperating so that said locking knob can be turned by hand totighten said lock nut against the inner cylindrical wall of said shellto lock said disc in position within the shell or to loosen said locknut and permit movement of said disc through manual shifting of saidlocking knob in the above-indicated manner.
 5. Holding means inaccordance with claim 4 in which said means for preventing substantialaxial migration of said disc from its predetermined position within saidshell includes said inturned flange at the forward end of said shell andat least two diametrically opposite projections from the innercylindrical wall of the shell positioned to prevent substantial axialmovement of said disc to the rear within said shell.
 6. Holding means inaccordance with claim 5 in which the registry of the enlarged portion ofsaid substantially circular opening at the forward end of said shell andthe slot in the forward face of said disc occurs at an extreme positionof rotation of said disc within said shell where the shank of saidlocking knob abuts one end of said perpendicular slot in the wall ofsaid shell, whereby said registry can be quickly and easily achieved forremoval of said tray from said clamping assembly.
 7. HOlding means inaccordance with claim 6 in which said clamp means comprises a pair ofhollow, generally cylindrical members of equal diameter, each having apair of diametrically opposite, semi-circular notches cut in its sidewall, the radii of the semi-circular notches being such as to permitsaid members to be brought together in embrace of said tubing so thattheir semi-circular notches form circular openings sized to snuglyreceive the tubing, one of said cylindrical members comprising saidouter shell.
 8. Holding means in accordance with claim 7 in which saidassociated fastening means for securing said clamp means tightly inplace on said tubing includes a pair of nonthreaded, cylindrical socketson one of said cylindrical members and a pair of threaded sockets on thesecond of said members, the positions of said nonthreaded cylindricaland said threaded sockets being such that the sockets fall intorespective alignment when the two members are in their positions ofembrace of said tubing, and said associated fastening means including,also, a pair of screws adapted to pass through said cylindrical socketsand into threaded engagement with said threaded sockets, when saidmembers are so positioned, the screws being of a length suitable fortightening in said threaded sockets to secure said clamp means tightlyin place on said tubing.
 9. Holding means in accordance with claim 8 inwhich said tray has at least one depression adapted particularly, foruse as a holding seat for a drink container.
